        The directory in which persistent metadata files are stored can now
        be configured.  By default persistent  metadata files are stored in
        the environment home directory.  The files that will be stored in
        the metadata directory are __db.rep.system, __db.rep.gen,
        __db.rep.egen and __db.rep.init.   
    </p>
      <p>
        To set the metadata file directory, call <a href="../api_reference/C/envset_metadata_dir.html" class="olink">DB_ENV-&gt;set_metadata_dir()</a> with
        the path to the directory in which to store metadata files.  The
        metadata directory can also be set in the
        <code class="literal">DB_CONFIG</code> file using
        <code class="literal">set_metadata_dir</code>.
